Claude Code can be configured to understand and respect your team’s pull request review checklist, helping maintain consistent code quality across your codebase. By setting up the right configuration files and providing proper context, you can make Claude Code an effective partner in your code review process.
Understanding Pull Request Checklist Context
Your team’s pull request checklist likely includes items specific to your codebase, coding standards, and project requirements. These might cover security considerations, performance criteria, testing requirements, and documentation standards. Claude Code needs to understand this context to provide meaningful assistance during code reviews and before you submit changes.
The most effective approach involves creating a CLAUDE.md file that documents your team’s review requirements. This file acts as persistent context that Claude Code references when working with your codebase.
Setting Up CLAUDE.md for Review Checklists
Create a CLAUDE.md file in your project root with your team’s pull request requirements. This file should contain specific criteria that Claude Code will consider when reviewing code or suggesting improvements.
# Project Review Checklist
## Security Requirements
- All API keys and secrets must use environment variables
- Input validation required for all user-supplied data
- Authentication checks must occur before any data access
- SQL queries must use parameterized statements
## Testing Requirements
- New functions require unit tests with >80% coverage
- API endpoints need integration tests
- Edge cases should have explicit test coverage
- Test files must use descriptive assertion messages
## Code Quality
- Functions must have JSDoc/TypeDoc comments for public APIs
- Error messages should be actionable and specific
- Magic numbers must be extracted to named constants
- Complex conditionals (>3 conditions) need early returns
## Documentation
- Breaking changes require CHANGELOG updates
- New dependencies need rationale in PR description
- Architecture decisions require ADR documentation
This configuration gives Claude Code clear criteria for evaluating code quality. When you run Claude Code in your project, it reads this file and applies these standards to its suggestions.
Creating Project-Specific Review Rules
Beyond the general checklist, your team may have specific rules for particular components or modules. Create targeted CLAUDE.md sections for different parts of your codebase.
# Backend API Module Rules
## Endpoint Requirements
- All endpoints must validate request schemas
- Response codes must follow REST conventions
- Rate limiting headers required for public endpoints
- Deprecation notices needed 2 releases before removal
## Database Rules
- Use transactions for multi-table operations
- Implement soft deletes where appropriate
- Add database indexes for frequently queried columns
- Migration files must be reversible
# Frontend Component Rules
## React Components
- Use functional components with hooks
- Memoize expensive computations with useMemo
- Extract custom hooks for reusable logic
- PropTypes or TypeScript types required
## State Management
- Local state for component-specific data
- Context for shared UI state
- Server state via React Query or SWR
- Avoid prop drilling beyond 2 levels
Using Review Context in Claude Code Sessions
When working with Claude Code, explicitly reference your checklist requirements. Start sessions by acknowledging the context:
I'm working on [feature description]. Please review my changes against our PR checklist: security requirements, testing standards, and code quality rules in CLAUDE.md.
This approach ensures Claude Code applies your team’s standards throughout the development process, catching issues before they reach formal review.
Integrating with GitHub Pull Requests
Claude Code can assist with GitHub-based code reviews when you provide the PR context. Use the GitHub integration to fetch PR details and then apply your checklist criteria:
# Clone the repository and checkout the PR branch
git fetch origin pull/123/head
git checkout FETCH_HEAD
# Run Claude Code to review changes
claude "Review these changes against our PR checklist in CLAUDE.md"
Claude Code will analyze the diff and identify areas that need attention based on your team’s standards.
Automating Pre-Submission Checks
Create a script that runs Claude Code against your changes before pushing:
#!/bin/bash
# pre-review.sh
echo "Running pre-submission review..."
git diff main...HEAD --stat > /tmp/changes.txt
claude "Review the changes in this diff against our team's PR checklist.
Focus on: security issues, test coverage, code quality, and documentation.
Report any concerns before I submit this PR."
Make this script part of your development workflow:
chmod +x pre-review.sh
./pre-review.sh
Handling Checklist Evolution
Your team’s checklist will evolve over time. Update your CLAUDE.md regularly to reflect new requirements, removed checks, and modified standards. Version control your checklist alongside your code:
git add CLAUDE.md
git commit -m "Update PR checklist with new security requirements"
This ensures every team member works with the same standards and new contributors can quickly understand expectations.
Best Practices for Effective Configuration
Keep your CLAUDE.md focused and actionable. Include specific, measurable criteria rather than vague guidelines. For example, instead of writing “write good tests,” specify what constitutes adequate coverage for your project.
Review and refine your checklist quarterly. Remove checks that rarely catch issues and add requirements when recurring problems emerge. Claude Code performs best when given clear, concrete expectations.
Document the reasoning behind critical checklist items. When team members understand why certain standards exist, they are more likely to follow them consistently.
Performance Checklist Items
Add performance-specific requirements to your PR checklist:
# Performance Requirements
## Database Queries
- No N+1 queries (verify with django-debug-toolbar)
- Use select_related/prefetch_related appropriately
- Query execution time <100ms for typical endpoints
- Queries logged and monitored in production
## Frontend Performance
- Bundle size <300KB gzip for initial load
- Lighthouse score >90 on mobile
- Core Web Vitals: LCP <2.5s, FID <100ms, CLS <0.1
- No console errors or warnings in production builds
## API Response Times
- 95th percentile response time <500ms
- P99 response time <1s
- Cache-friendly: use ETag and Last-Modified headers
Claude can now suggest optimizations before code reaches review.
Testing Strategy Requirements
Specify exactly what testing coverage means for your team:
# Testing Requirements
## Coverage Minimums
- New code: 80% line coverage minimum
- Existing code: No reduction in coverage
- Integration tests for all API endpoints
- E2E tests for critical user flows
## Test Patterns
- Use factory-boy for test data
- Test both happy path and error cases
- Use descriptive assertion messages
- Avoid mocking external APIs (use fixtures instead)
## Performance Tests
- New endpoints must include load test (target: 1000 RPS)
- Memory leaks detected by running under load
- Database migration timing tested
Documentation Requirements
Specify what documentation changes trigger PR requirements:
# Documentation Checklist
## Required for New Features
- API documentation updated (SwaggerUI/OpenAPI)
- Runbook created for operational concerns
- Architecture decision recorded if applicable
- User-facing changes documented in changelog
## Required for Modified Features
- Breaking changes documented with migration guide
- Deprecation timeline specified for removed features
- Performance implications documented
This ensures documentation stays current without manual reminders.
Dependency Management Rules
Define how your team handles dependency changes:
# Dependency Management
## Adding Dependencies
- Security vulnerability history checked
- Package size <500KB gzip
- No duplicates with existing functionality
- License compatibility verified (MIT/Apache preferred)
## Version Updates
- Patch versions: auto-merge if tests pass
- Minor versions: require manual review
- Major versions: require architectural review
- Deprecation warnings fixed before upgrade
Claude can flag dependency additions that violate these rules.
Multi-Environment Configuration
Specify requirements for code that touches multiple environments:
# Multi-Environment Requirements
## Development
- Uses local configuration, zero production secrets
- Database can be reset without impact
- Can run without internet connection
## Staging
- Identical configuration to production
- Uses production-like data volumes
- All external service integrations tested
- Performance tested under expected load
## Production
- All secrets stored in secure vaults
- Deployment is reversible (via canary or blue-green)
- Database schema changes are backward compatible
- Monitoring alerts configured before deployment
Error Handling Standards
Define error handling patterns your team requires:
# Error Handling
## API Errors
- All errors include correlation ID for debugging
- Error messages are actionable, not generic
- Stack traces never exposed to clients
- Appropriate HTTP status codes used
## Logging
- Structured logging with consistent field names
- Sensitive data redacted (passwords, tokens, PII)
- Error level logs include stack traces
- Request/response logging for debugging
## Monitoring
- Alerts configured for error rate increase
- Fallback behavior defined for external service failures
- Graceful degradation tested
Commit Message Standards
Include specific guidance on commit message format:
# Commit Message Format
Required format:
